--just from this blood work.

The gold standard for celiac is still an intestinal biopsy that shows flattened villi, which is different from the type of inflammatory infiltration usually found in Crohn's, but there are plenty of people who have both. Moreover, there are people with negative blood work who show up with flattened villi, people with positive blood work who don't--they may have a form of gluten sensitivity that involves primary symptoms that are neuromuscular in nature, rather than gastric--or, the villous samples may be on the way to damage, but not show it unequivocally yet . . .

In any case, it won't hurt to try to eliminate certain classes of foods to see if it helps your symptoms. Generally one tries to eliminate one class of foods each week to see what effect that has. One can conversly eliminate practically everything--basically go on an applesauce, white rice and broth diet--and then add foods back in to see what causes reactions.

The key here is that no one needs a physician's imprimatur to alter diet.
